The PSLV is an expendable launch system developed by ISRO to launch Indian remote sensing satellites. It holds the record for launching the most satellites at once, 10 in 2008. As of 2012, PSLV had a 95% success rate over 22 flights. PSLV-C20 successfully launched 7 satellites from 6 countries into a sun synchronous polar orbit in February 2013, earning ISRO 100 crore rupees. Upcoming PSLV missions include launches in May and October 2013 to deploy Indian satellites.

4. It’s history The Polar Satellite Launch Vehicle, usually known by
its abbreviation PSLV, is an expendable launch system
developed to allow India to launch its Indian Remote
Sensing(IRS) satellites into sun synchronous orbits,
a service that was, until the advent of the PSLV,
commercially viable only from Russia. PSLV can also
launch small satellites into geostationary transfer
orbit (GTO).
In April 2008, it successfully launched 10
satellites at once, breaking a world record held by Russia.
 On 9 September 2012 the PSLV flew its 21th consecutive
successful launch mission.Its only failure in 22 flights
was its maiden voyage in September 1993, providing the
rocket with a 95 percent success rate.

5. A brief description of PSLV-C(20) :-

6. Typical Parameters of PSLV
 Lift-off weight -295 tonne
 Pay Load-1600 kg in to 620 km Polar Orbit,
1060 kg in to Geosynchronous Transfer Orbit (GTO)
 Height-44 metre

9. 1’st launching-UNSUCCESSFUL!!
 The PSLV had its first launch on 20 September 1993. Although all main engines
performed as expected, an altitude control problem was reported in the
second and third stages.

10. Efficiency of PSLV After this initial setback ISRO met complete success with the third
developmental launch in 1996. Further successful launches followed in
1997, 1999, and 2001.
 PSLV continues to be the work horse of Indian satellite launches,
especially for LEO satellites. It has undergone several improvements with
each subsequent version, especially those involving thrust, efficiency as
well as weight.

11. Successful launches with PSLV As of February 2013 the PSLV
has made 23 launches, with 21
successful, one failure and
one partial failure

12. PSLV-C(20)
-101th launch creates a history…

13. PSLV-C(20)
-launched 7 satellite successfully
 On 25 February 2013 PSLV-C(20) successfully
launched 7 satellites from the First Launch Pad of
Satish Dhawan Space Centre SHAR (SDSC SHAR),
Sriharikota.
 launches the Indo-French satellite SARAL along
with six commercial payloads from Canada,
Austria, Denmark and UK into a 785 km polar sun
synchronous orbit inclined at an angle of 98.538
deg to the equator.

15. Benefit in Indian economy …
# SPOT-6(the satellite launched by PSLV-C(21) on
sep. 9,2012) is the biggest commercial lift so far
since India forayed into the money spinning
commercial satellite launch services.
# PSLV –C(20) earned 100 cr. For launching 7
commercial satellite from foreign country.

16. Planned launches with PSLV PSLV-HP (C22) on May 2013 TBD
with 1380 kg satellite.
mission named as IRNSS-1
 PSLV-XL 25 on October 2013 with
TBD satellite.
mission named as Mangalyaan
 These two satellites are totally
developed by ISRO.

17. Congratulations to our scientists
 The launch of this PSLV
adds yet another golden
milestone in the success
story of Indian space
history ... The credit for
this achievement,
undoubtedly, goes to our
scientific community,
particularly those working
with ISRO..
